Closing unit for an injection molding machine

A closing unit for an injection molding machine comprising a substantially C-shaped machine frame, to the one leg of which is mounted a stationary mold mounting plate and to the other leg of which is mounted a closing mechanism for driving a moveable mold mounting plate in a longitudinal direction of the machine frame, wherein the free ends of the legs of the machine frame are deformed under the influence of the closing force occurring during the closing operation, and wherein the stationary mold mounting plate is supported at or near its lower edge by way of a support element on the machine frame against the closing force and is fixedly connected above the lower edge to the one leg, wherein the support element has a flexural beam extending transversely relative to the longitudinal axis of the machine and a compression bar extending in the direction of the longitudinal axis of the machine, wherein the flexural beam is connected free from backlash to the machine frame, preferably being screwed thereto.
